What makes a car "intelligent" in today’s era of rapid technological evolution? Is it the sleek design, the infotainment system, or perhaps the promise of autonomous driving? At the heart of this transformation lies a game-changer: AI semiconductors. These advanced chips are transforming vehicles into intelligent machines capable of making real-time decisions, enabling safer, more efficient, and increasingly autonomous transportation.
Powering Sustainable Mobility
The global shift toward sustainable transportation has brought electric vehicles (EVs) into the spotlight, and semiconductors are pivotal to their functionality. These advanced chips optimize lithium-ion batteries, enhancing their lifespan, efficiency, and performance, while enabling fast and effective charging solutions. In EVs, semiconductors are critical for managing battery systems, sensors, and infotainment platforms.
The Indian Semiconductor Market Landscape
The Indian automotive semiconductor market is projected to grow at a CAGR of 9.59% during the forecast period from 2025 to 2032. As a global leader in the production of tractors, two-wheelers, and three-wheelers, India’s automotive sector is experiencing substantial demand for semiconductors. The expanding middle-class population and increasing demand for passenger cars are significant drivers of this growth.
Semiconductors in India serve various end-use sectors, including telecommunications equipment, information technology, office automation (IT & OA), and mobile devices. The growing adoption of the Internet of Things (IoT) is further expected to elevate the need for intelligent computing, adding momentum to the semiconductor demand in the country.
The Backbone of Autonomous Driving
Autonomous vehicles (AVs) represent the pinnacle of AI semiconductor application. These vehicles rely on semiconductors to process vast amounts of real-time data, integrating inputs from sensors such as LiDAR, radar, and cameras. This processing capability creates a comprehensive understanding of the vehicle’s surroundings, ensuring precise navigation, hazard detection, and rapid decision-making. AI semiconductors also enable vehicle-to-everything (V2X) communication, forming the backbone of intelligent transportation systems (ITS). By facilitating communication between vehicles, infrastructure, and other road users, these chips enhance traffic management, reduce congestion, and improve road safety. This technology is integral to the development of safer and more efficient transportation ecosystems, paving the way for a fully autonomous future.
Pioneering Compute Architectures for Smarter Vehicles
The evolution of automotive compute architectures has been a response to the increasing complexity of modern vehicles. The industry has transitioned from centralized designs to domain-based systems and, more recently, zonal architectures. Each approach is tailored to optimize data processing and functionality:
Centralized Architectures: Consolidate computing resources for advanced applications like autonomous driving, offering higher processing power and better integration.
Domain-Based Systems: Focus on specific vehicle functions such as infotainment or Advanced Driver Assistance Systems (ADAS), ensuring optimal performance in those areas.
Zonal Architectures: Distribute computing tasks across zones within the vehicle, enhancing scalability and flexibility while reducing wiring complexity.
Among these advancements, Chiplet Systems have emerged as a transformative innovation. By disaggregating System-on-Chips (SoCs) into smaller, functional units, Chiplet architectures enable modularity and scalability. This approach allows manufacturers to customize designs for specific vehicle requirements, reducing costs and improving efficiency, making them indispensable for next-generation vehicles.
